These are permanent magnet motors ?? Are the magnets intact and not cracked? If the magnets are cracked or damaged the motor will not run. Other than that, they are straight forward, either work or not! If they are wound motors and not permanent magnets, then the windings and the armatures need to be checked for shorts.
